SAN DIEGO – Inland residents might need to crank up the air conditioning one more day, but Saturday should be significantly cooler.

“We'll try to get back to normal by the end of the weekend,” said Tina Stall, a meteorologist with the National Weather Service. “There will be even more cooling Monday.”

On Friday, highs could reach the low 90s in the inland valleys and the high 70s to low 80s along the coast. High clouds from what's left of Tropical Storm Linda could drift over the county, but no rain is expected.

By Saturday, the high pressure over Nevada that caused the mini heat wave should start to break down and move to the north. Temperatures should drop to the low 80s inland and the mid-70s at the beaches. Morning and evening low clouds and fog are forecast to return near the coast. Temperatures should be similar Sunday.

There's a slight chance of thunderstorms in the mountains and deserts through the weekend. The mountains should be around 90 Friday, then cool 5 degrees both Saturday and Sunday. The deserts should reach about 108 on Friday, then drop to about 100 on Sunday.

On Monday, the jet stream is expected to dip into Central California, and that should help drop temperatures even more. Highs at the coast should be in the low 70s, and the valleys may not make it to 80.
